DETAGHABLE RIM FOE WHEELS OF ROAD-VEHICLES.

Specification of Letters Patent.

To all whom it WLdj/fiO/M'flit.

lle it known that l. ARTHUR FREDERICK .(luxsroxn, a subject of the King of England. residing. at Bath, in thecounty of Somerset, England, have invented certain new and useful Improvements in Detachable liars for lVheels of Road-Vehicles, of which the following is a specification.

' telly.

The invention furthei r relates to details of construction and apreferred form of carrier hereinafter fully described with reference to the accompanyingdrawings wherein- Figure l is a transverse section of the wheel telly showing the rim in position, Fig. 2 is a perspective view of the wheel with the rim removed. Fin. is a perspective view of the wheel. riindetached from thei'elly. Fig. l a transverse section-of the wheel -telly showing; a slightly modified construction of rim which falls within the scope this invention, and is a perspective view of a wheel rim secured to a vehicle by a rotatable carrier.

Like letters ii'idicate like parts throughout the crawinn's.

A, wheel A has a :telly B that is surrounded by a metal band C that .is cylindrical in form and has a step C on the inner edge. l'loles D are drilled transversely through the telly and on the inner side opposite the holes are secured screw-threaded sockets I l. The telly is smiled at l to receive the tire valve and a slotted. l -shaped strcueithening plate G is provided at this point. The plate is secured hy screws that. enter the telly from two difi'erent sides.

2%, wheel rim H has an inwardly directed side flange H that has in it holes H which register with the holes l) in the telly. The flange H has an L-? raped cross section and is riveted to the inside oi the rim H thereby forming a step 3 at one edge. The bearing face J of this step c lindrical and makes a tight fit with the corresponding cylindrical face of the band. Also the bearing lace H on the opposite side of the rim is cylindrical and makes a tight fit with the cylindrical face provided by the step C or the band.

Secured to the flange H are two screwthreaded lugs K, one being placed near the tire valve and the other approximately opposite thereto. The operation of this device is as fol lows :lhe rim H is passed over the telly fromthat side shown at the right in Fig. 2 (which for convenience may he called the near side, as this is always toward theoporator) until its edge strikes the near side of the step C Bolts M are then introduced through the holes H in the flange and holes D of the telly and screwed into the sockets E. These bolts draw the rim forcibly on to the telly, so that it finally assumes the position shown in Fig. 2 and is securely held by lfiatcnted Jan. 6, 191%. Application filed April 14, 1910. Serial No. 555,482.

its tight fitand by means of the bolts. As

will be seen the step .on the folly and the step on the rim leave a central space be tween the rim and telly which, however, is not novel as rims with steps leaving a cental space have before been employed. To detach the rim from the telly the bolts M are unscrewed and one or more of the same screwed into the lugs K until their ends hear against the telly and force the rim therefrom. One of the lugs being near the valve the L -shaped plate will form a good bearing for the end of the screw.

Instead of riveting the inwardly directed flange ll: to the rim. the flange may he ables the rim to stretch more than would he the-case it it were turned from a casting.

It is found that with a telly 23 inches in diameter a rim can be used whose shortest interior diameter is 23 inches. These dimensions are only given by way of ex ample. as the precise relative sizes will vary according to circumstances.

llill To enable the rim with a tire thereon to flange H may be useclfor securing it to a suitable support. The support preferred is a carrier that conveniently takes the form r. a double arm ll pivoted at its center by f a bolt N to a bracket (3. The arm s kept in place on the bolt lil by a nut N ch may he tiglilened to l id the arm N l or loosened to allow it to rotate about the bolt. At the coals of the arm ll are sewer-threaded orifices I To secure the rim to the arri it is plea-e5 over the ends of the arm so that they bear against the side flange H Bolts are inserted tl'irough the holes in the flange and .ecrewel into the orifices of the carrier, thus holding the rim rigidly in place. It Will be seen that a tire While on the rim and secured in this .anner to me carrier can be readily repaired. access can be had to all parts of the tire and the Whole conveniently rotated by turning the double arm UT of the carrier about its central pivot.

hat I claim as my invention and clesire to secure hylletters Patent is l. The combination of, a felly of a Wheel having a eylinelrieal face at that side of its outer periphery" that is farthest from the vehicle and having an enlarged cylindrical step an the other side of such enter periphery, land thereon conforming to the shape of l e Eelly anal a detachable tight-fitting encllee rim surrounding such hen having a cylindrical face to engage the step, a cylindrical rib or step to engage the smaller cylindrical portion of the frilly-band, an in wardly clirectecl portion on the rim that engages the side face of the felly and is pr0- vided with. holes registering With holes in the felly threaded socketssecurecl to the folly in line with the holes thereineand on the side opposite to the said inwardly (lirected portion, and bolts passing through the said registering holes and screwing into the said sockets for the purpose of securing the rim to the folly, substantially as set forth.

2. In a. detachable rim for a road-Wheel, the combination of, a tii'ecarrying endless rim that slides axially onto or from the folly of the Wheel, the latter being slotted to receive the valve of the tire, the rim having an inwardly directed portion fHOVlCled with a screw-threaded orifice that is placed at one side of but in close proximity to the slot, and a belt for forcing the riinfrom. the felly by inserting it in the screw-threaded orifice, substantially as and for the purpose set forth. 7

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
